My dad took a job on a surveying crew based near Leadville, Colorado after he was discharged from his WWII ETO service. He hunted with a "bring back" Mauser 98 open-sighted 7x57 rifle and 175 grain round nose bullets. He took one elk with it during his two years in Colorado. Don't know details of the hunt, but likely it wasn't too far (<150 yards???). I do remember that the elk was taken with one shot.
It worked.
